摘　　要：介绍了数字光学成像技术在电力工程勘测应用中的适用性和优点,阐述了全景式钻孔电视成像系统的测试工作原理和工作流程,通过全景式钻孔摄像给出了全孔的孔壁展开图和三维虚拟岩芯图,对深层岩脉、节理、裂隙的产状和宽度进行量化统计,达到了定量分析钻孔节理裂隙几何特征的目的。应用数字光学成像技术于岭澳核电三期的边坡工程中,查明了边坡工程场区的主要岩层结构面和岩体完整性,通过对比常规勘测手段获得的节理裂隙发育规律,验证了全景式钻孔摄像的可靠性,表明该技术可较好地应用于核电工程中。The applicability and advantages of Digital Borehole Optical Technique in power engineering survey are reviewed, the basic principle and testing process of the Digital Panoramic Borehole Camera System from hardware to software are discussed. By the borehole wall unrolled images and 3D virtual borehole core images form Digital Panoramic Borehole Camera, the occurrence and width of the deep dikes, joints and fissures are quantitatively described and the quantitative analysis of geometric features of borehole is warranted. The Digital Borehole Optical Technique is applied into the slope project of LingAo nuclear plant at its 3rd stage, and the main structural planes and rock mass integrity are found out. The reliability of Digital Panoramic Borehole Camera is confirmed through comparing its image with the statistic distribution of developmental joint fissure by conventional survey methods. The results show that it has good application prospect in nuclear power project.
